> Literally no one does that. You are imagining things.
You are obviously not a serious participant here. These people exist. They existed before the internet, and the internet has, to my great disappointment, only enabled their spread.
There's a ton you could read, but maybe start with Neiwert's "God's Country" and "Alt-America", which document the pre- and post-Internet versions of America's white supremacist movement.
> Abusive is a relative and in this context meaningless word.
That is also embarrassingly ignorant. If you'd like to learn something, maybe try Citron's "Hate Crimes in Cyberspace", Warren's "Targeted and Trolled", Jeong's "The Internet of Garbage", and Bancroft's "Why Does He Do That".
